Marcus Wins! Big Deal, So Does Everybody.

But it turns out it’s no big deal, because Marcus says “Everyone Wins!”

In his new study of that title, I mean. Marcus finds that charter schools are improving regular public schools in NYC by creating healthy competitive incentives. The effect is small, fitting the overall pattern in the research – charters typically don’t give you as big a boost as vouchers, but having them is better than not.

For all you Rawlsians out there in JPGB-land, Marcus also finds that the lowest-performing students in NYC’s regular public schools benefit from charter competition; in fact, while the benefits for the overall population are statistically certain only in reading, they’re certain in both reading and math for low performers.
